Lewmar Fiddle Blocks

Lewmar Synchro Fiddle Blocks are used in purchase systems to allow the trimmer to sheet in higher loads with ease. The Fiddle Blocks can be attatched onto the boom
giving you a powerful purchase on your main block and tackle.

Synchro blocks from Lewmar are engineered for speed, efficiency
and superior handling. These blocks suit a range of purposes from
performance cruising yachts to specific high-load low-movement applications
on racing
sailboats. Lewmar uses a combination of scientifically optimised
block geometry, a Free-Spin bearing and self-aligning head to reduce
friction and increase
efficiency by up to 40% over budget blocks on mainsheet systems.
